We just need to find out what is 1% of 1500 We do that by multiplying them by each other. but first lets change 1% into a decimal. 1% = 0.01 Now we multiply 1500 x 0.01 = 15
Since they are asking to increase 1500 we add 15 sooo
You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)
