Match each vehicle's travel scenario with its calculated average speed in miles per hour (mph).

A patrol boat travels $65$ miles in $130$ minutes. $30$ mph
A military convoy travels $112$ miles in $2$ hours and $48$ minutes. $40$ mph
A supply train covers $135$ miles in $2$ hours and $15$ minutes. $60$ mph
A reconnaissance aircraft covers $384$ miles in $2$ hours and $24$ minutes. $160$ mph

Match the scenarios to their respective speeds by converting all times strictly into hours, then dividing the distance by that time.

Each correct speed is found by converting the travel time into decimal or fractional hours and then properly applying the standard rate formula (

r = d/t

Convert the travel time in each scenario to hours.

Boat: 13/6 hours. Convoy: 2.8 hours. Train: 2.25 hours. Aircraft: 2.4 hours.

Because the required speed is in miles per hour (mph), the units of time must be strictly in hours.

Apply the speed formula: Rate = Distance / Time.

Boat: 65 / (13/6) = 30 mph. Convoy: 112 / 2.8 = 40 mph. Train: 135 / 2.25 = 60 mph. Aircraft: 384 / 2.4 = 160 mph.

Dividing the given distance in miles by the correct time in hours yields the average speed.
