In one day, there is 24 hours, so in 5 days, there is 120 hours. As you've got this information, you've then got to multiply the two numbers together. 28,325*120= 3399000 Therefore, the space shutt;e travels 3,399,000 miles in 5 days Hope this helps :)
First to find out the hours times 24 (as there are 24 hours in a day) by the number of days 24x5=120 Then times the hours by the speed 28,325*120=3399000 that will be the amount of miles it will have travelled in the time
