Question

A scooter is running at a speed of 45km per hour.How much distance will it cover in 18 second?

Answer 1

Answer:

100 m

Step-by-step explanation:

Speed = 45 km / h

Find the distance covered in 1 second:

1 hour = 45 km

1 min = 45 ÷ 60 km = 0.75 km

1 sec = 0.75 ÷ 60 = 0.0125 km

Find the distance covered in 18 seconds:

1 sec = 0.0125 km

18 sec = 0.0125 x 8

18 sec = 0.1 km or 100m

Answer: 100 m

Answer 2

first of all convert the speed in m/sec which will be 45×1000÷3600=12.5m/sec

therefore it will cover speed × time

=12.5×18

=225m
