Question

Ned is driving at 72km/h, at this rate how long (in hours and minutes) will it take him to drive 210km

Answer 1

2 hours 55 minutes

Explanation:

calculate time (T) using the relationship

T =
`(D)/(S)` ( D is distance , S is average speed )

T =
`(210)/(72)` = 2.9166... hours

to convert to hours and minutes multiply the decimal part by 60 , that is

0.9166.. × 60 = 55 minutes

then time taken to drive 210 Km is 2 hours 55 minutes
