Question

3. lit If a man takes 3 min to walk down a street 258 m long, find his speed in km/h.
(ii) A car covers 300 m in 20 s. Find its speed in km/h.​

Answer 1

Step-by-step explanation:

1. spead = distance / time

spead = 258 / 3

spead = 86 km per h

2. spead = distance / time

• 60 s = 1 m
• 20 s = 1/20 m

spead = 300 / 1/20
