In order to improve your skill in answering speed distance time questions, there are two main things you can do.įirst, make sure that you are really familiar with the formula triangle. 20 30 =50, so she travels 50 miles in total. In the second half, she travels 30 miles, (20 x 1.5 = 30). How far does she travel in total?Īnswer: In the first half of her journey she travels 20 miles (10 x 2 = 20). In the second half, she travels at 20mph for 90 minutes. In the first half of the journey, she travels at 10mph for 2 hours. If we convert this into hours and minutes, it will take her 1 hour and 4 minutes to run 8km. If she runs 10km at 7.5kph, to work out the time, you need to divide 8 by 7.5, which equals 1.066. If she maintains the same speed, how long would it take her to run the 8km race?Īnswer: Her speed is 7.5kph.
