Distance covered = 240×
60

=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60×

Answer:
28.33 km
Step-by-step explanation:
The car travels 50 km in 60 minutes. So, divide 50 by 60= 0.833. Then multiply by 10= 8.33.
Next, the car travels 60 km in 60 minutes. So, divide 60 by 60= 1. Then multiply by 20= 20
20+8.33= 28.33
So, the car traveled 28.33 km
