Question

A bus travels 54 km in 90 minutes. The speed of the bus is

A) 0.6 m/s

B) 1 m/s

C) 5.4 m/s

D) 10m/s​

Answer 1

Distance=54km

=>54*1000=54000m

Time=90min.

=>90*60=5400sec.

speed=

$\frac{distane}{time}$

=>⁵⁴⁰⁰⁰/5400

10m/s

Answer 2

Answer:

10m/s

Step-by-step explanation:

Speed = distance/time.

Given,

Distance = 54 km

convert km to m

Distance = 54 × 1000 m

= 54000 m

Time = 90 min

convert minute to second

Time = 90 × 60 s

= 5400 s

Therefore, Speed = Distance/time = 54000 m/5400 s = 10 m/s
