Question

A car moves with a speed of 60 km/h for 20 minutes and then moves with a speed of 30 km/h for the next 20 minutes, find the total distance covered by the car.

Answer 1

answer: 30 km

Step-by-step explanation:

S1=60kmph

T1=20 min

= 20/60 hr

=1/3 hr

D1=?

Speed=distance/ time

Distance=speed×time

Distance =60km/h × 1/3hr

D1 = 20 km

S2=30kmph

T2=20 min

=1/3 hr

D2=?

D2=30km/h × 1/3 hr

D2=10km

total distance covered by car = D1+D2

=20km+10km

=30km

.

. . total distance covered by car =30 km
