75kmph

Explanation:

First simplify the 7200 second into minutes. #7200/60= 120#. Then simplify into hours. #120/60=2#. Finally divide the total distance(150km) by the time it took to cover that distance to find the kmph(kilometers per hour). #150/2=75# The final answer is 75kmph.

#"75 kmph"#

Explanation:

#"Speed" = "Distance"/"Time"#

#v = "150 km"/"7200 s"#

#v = "150 km"/(7200 cancel"s" × "1 hour"/(3600 cancel"s")) color(white)(xx)[∵ "1 hour = 3600 seconds"]#

#v = "150 km" / "2 hour" = color(blue)"75 kmph"#
