A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. The total distance covered by the car is:

A

100 km

B

25 km

C

15 km

D

10 km

Text Solution

AI Generated Solution

To find the total distance covered by the car, we can break it down into two parts based on the speeds and times given. ### Step 1: Convert time from minutes to hours The car travels for 15 minutes at each speed. Since speed is given in km/h, we need to convert the time from minutes to hours. \[ \text{Time in hours} = \frac{\text{Time in minutes}}{60} \] ...
