Question

A car takes 30 minutes to cover a distance of 20 km. Calculate its speed in km/h and
m/s.

Answer 1

Answer:

km/hr= 40, m/sec= 11 1/9

Step-by-step explanation:

Time=30 min

Distance=20 km

Speed=x

speed= distance/time

time= 30min = 30/60

S= D/T

x= 20÷ 30/60

x= 20 × 60/30

x= 40 km/hr

40 km/hr × 5/18 = m/sec

= 20× 5/9 = m/sec

= 100/9 = m/sec

= 11 1/9 m/sec
