Answer 1

Correct Question:-

A car moves with a speed of 60 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. The total distance covered by the car is

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Answer:-

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:

▪︎Speed of car for first 15 min = 60km/h

▪︎Speed of car fot next 15 min = 60km/h

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:

▪︎Total distance cover by car in total time

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

Distance cover by car in first 15 min

= Speed × Time

= 60 × $\frac{15}{60}$

= $\cancel{60}$ × $\frac{15}{\cancel{60}}$

= 15 km

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Distance cover by car in next 15 min

= Speed × Time

= 60 × $\frac{15}{60}$

= $\cancel{60}$ × $\frac{15}{\cancel{60}}$

= 15 km

⠀⠀⠀⠀⠀⠀⠀⠀⠀

So, Total distance covered in total time

= (15 + 15)km

= 30km

More Formulas to know:-

▪︎Speed = Distance ÷ Time

▪︎Time = Distance ÷ Speed

▪︎Distance = Speed × Time
