Mandy runs 4km in 18min. She plans to run in a 15km race. How long will it take her to complete the race?
distance = rate x time
distance - 15 km
time = solve for this
rate = 4km/18min
4km/18 mins = 1km/4.5 mins so
15 kms x 4.5 mins = 67.5 mins
= 1 hr 7 mins 30 secs

To solve this problem, we need to use the formula: distance = rate x time.
Given that Mandy runs 4km in 18 minutes, we can find her rate by dividing the distance by the time:
Rate = 4km / 18min = 0.222 km/min.
Now that we have Mandy's rate, we can use it to find the time it will take her to complete the 15km race:
Time = Distance / Rate = 15km / 0.222 km/min ā 67.57 minutes.
Therefore, it will take Mandy approximately 67 minutes and 34 seconds to complete the race.
