How long does it take to travel 84.2km
at 80 kph
Answered by Jai
recall that speed is distance travelled per unit of time, or
v = d/t
substituting,
80 = 84.2 / t
80t = 84.2
t = 84.2/80
t = 1.0525 h

hope this helps~ :)

Time = Distance/Speed
= 84.2 km/(80 km/h) = 1.0525 hours
= 63.15 minutes
= 63 minutes and 9 seconds
