Question

A car travels at a speed of 60 km per hour. Find the distance (in cm) travelled by car in 4 hours.​

Answer 1

Distance = Speed × Time

=60 × 4

= 240 km

1km = 10^5 cm

240km = 2.4 × 10^7 cm

Hope this helps you!!

Answer 2

Answer:

2.4 x 10⁷ cm [24000000 cm]

Step-by-step explanation:

Given,

Speed = 60 km/hr

Time = 4 hr

So,

Distance = Speed × Time

= 60 km/hr × 4 hr

= 240 km

We know,

1 km = 1000 m

and, 1 m = 100 cm

So, 1 km = 1000 × 100 = 100000 cm = 10⁵ cm

Therefore, 240 km = 240 × 100000 cm

= 24000000 cm

= 2.4 × 10⁷ cm
