2. Marissa drives for 3 hours at 60 km per hour maricel drives 260 km in in 4 hours how far would would marissa travel if she drove 3 for 3 hours at the same speed as maricel?
3. Alfred drives for 1 and 1/2 hours at 75 km per hour then drives 120 km at 60 km per hour and finally drives for 30 minutes at 65 km calculate her average speed for the whole journey?
4. Steven robe from place a to place b at an average speed of 50 km per hour at the same time joseph drove from place b to place a at an average speed of 60 km using the same route if the distance between a and b were 300 km what is the distance between steven and joseph after 1 and 1/2 hours?
5. An owner jeep traveling at an average speed of 70 km left the town at 2:00 p.m. if it arrived in another town at 6:00 p.m. how far are the two towns?
Step-by-step explanation:
2. Maricel drives at a speed of \( \frac{260}{4} = 65 \) km/h. If Marissa drove at the same speed for 3 hours, she would cover \( 65 \times 3 = \text{195 km} \).
3. Alfred's total journey time is \( 1.5 \) hours + \( \frac{120}{60} = 3 \) hours + \( \frac{30}{60} = 0.5 \) hours = 5 hours. The total distance traveled is \( 1.5 \times 75 + 120 + 0.5 \times 65 = 112.5 + 120 + 32.5 = 265 \) km. Therefore, the average speed is \( \frac{265}{5} = 53 \) km/h.
4. After \( 1.5 \) hours, Steven covers \( 50 \times 1.5 = 75 \) km, and Joseph covers \( 60 \times 1.5 = 90 \) km. Since they are traveling towards each other, the distance between them after \( 1.5 \) hours is \( 300 - (75 + 90) = 135 \) km.
5. The total travel time is 6 hours - 2 hours = 4 hours. At an average speed of 70 km/h, the distance covered in 4 hours is \( 70 \times 4 = \text{280 km} \). Therefore, the two towns are 280 km apart.
