There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. Speed is a ratio of distance and time and both are required to calculate the speed. You have given only the distance.
4 miles in 18 minutes = 13.33... miles per hour.
Just divide the distance by the speed.
'A' is slower. 'B' is faster. 'A' covers 220 miles, while 'B' covers 310 miles. 'B' gained 90 miles on 'A'. Since 'B' gains 18 miles on 'A' in each hour, it took (90/18) = 5 hours for 'B' to gain 90 miles on 'A', so both stated distances were covered in 5 hours. Speed of 'A' = 220/5 = 44 Speed of 'B' = A+18 = 310/5 = 62
18 miles on the bicycle, 60 miles on the motorboat.
Depending on the speed of the vehicle, if you are going 60 miles an hour you will be driving for 1hr. and 18 mins Depending on the speed of the vehicle, if you are going 60 miles an hour you will be driving for 1hr. and 18 mins
speed: 54 miles in 3 hours = 18 miles per hour.
The top speed of the 1980 Renault 18 car is 94.4 miles per hour.
18 miles per second. (Well, that's the Earth speed in its solar orbit.)
Distance = Speed * Time = 54*3 = 162 miles.
Speed is distance over time. Without knowing the speed, we cannot calculate this.
The plane's speed is 6.136363636 mph.
