A train travels for 240 minutes to travel a distance of 220 miles. Assuming the trains speed is constant, what is the train's speed in miles per hour?
For this we require the distance-speed-time triangle which is defined as follows:speed = distance/time.However for the we need to convert the time into hours as that's what the question requires.there is 60 mins in a hour so (240/60)=4 hours of travelnow substituting in to the equation above we getspeed = (220/4)= 55 miles per hour which is the speed of the train
