Question

Tatenda takes t seconds to mow a square meter of lawn and Ciara takes c seconds to mow a square meter of lawn. Tatenda mows 700 square meters of lawn per week and Ciara mows 750 square meters of lawn per week.Write and expression describing how many more seconds Tatenda spends than Ciara mowing the lawn during 4 weeks.

Answer 1

2800t - 3000c

Step-by-step explanation:

Time it takes Tatenda to mow 1 square meter = t

Time it takes Ciara to mow 1 square meter = c

In one week, Tatenda mows = 700 square meters

in 4 weeks, Tatenda will mow = 4(700) square meters

In one week, Ciara mows = 750 square meters

in 4 weeks, Ciara will mow = 4(750) square meters

For time it takes for both:

Time for Tatenda = 4(700) × t

Time for Tatenda = 2800t

Time for Ciara = 4(750) × c

Time for Ciara = 3000c

Number of seconds Tatenda spends than Ciara mowing the lawn during 4 weeks:

Time for Tatenda - Time for Ciara = 2800t - 3000c

The expression describing how many more seconds Tatenda spends than Ciara mowing the lawn during 4 weeks is 2800t - 3000c
