Lelia makes $45 in profits
Because: you first have to find what x 4= 60 (15)
then you multiply that by 3 and you get the answer
( 15x4=60- Jo's profit
15x3=45- Leila's profit)
Please reformat your question so that I can try to help.
There is 3600 seconds per hour.
Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.
4.9 * 3600 = 17,640 miles per hour
17,640 x 1.6 = 28,224 kilometers per hour
