Answer:
Step-by-step explanation:
Given that,
Speed of toy car is 4 miles per hour
S=4mph
And the distance travelled is 9miles
d=9mi
Time taken?
So, speed is given as
Speed = distance / time taken
S=d/t, make t subject of formua
S×t=d
t=d/S
t=9/4
t=2.25 hours
t= 2 hours ¼hour
1hour =60mins
t= 2hours ¼×60mins
t=2hours 15mins
Or
1 hour is 60mins
t=2.25×60 =135mins
t=60mins+60mins+15mins
t= 1 hour + 1 hour + 15mins
t=2hours 15mins
