Question

a man walks at a speed of 4.8 km /hr and a tortoise travel at a speed of 20 cm/min.what per cent faster the man as compared to the tortoise​

Answer 1

Step-by-step explanation:

Speed of man =4.8 km /h

=4.8×1000m/h

=4800m/h

=4800×100cm/h

=480000cm/h

=480000÷60cm/min

=8000cm/min

Speed of tortoise =20cm/min

How many times is the speed of man more than that of tortoise=8000÷20

=400

Percentage = 400×100

=40000%
