Question

Mr. White drives 55 km a day for work. How many km will he drive in:
a. 5 days? Write an expression to represent the number of km he will drive in d days. Mr. White traveled a total of 990 km to work one month. How many days did Mr. White
travel to work that month. Write and solve an equation to represent this scenario.

Answer 1

Step-by-step explanation:

Given:

• Mr. White drives 55 km/day

To Find:

1. Distance travelled in 5 days
2. An expression that represents distance travelled in d days
3. Number of days to travel 990 km
4. An equation that represents the scenario

Solution:

1. Since, In 1 day 55 km is driven.

Hence, In 5 days = 55×5 = 275 km

Therefore, he'll drive 275 km in 5 days.

2. Hence, Distance travelled in d days = 55×d = 55d

Therefore, an expression that represents distance travelled in d days = 55d

3. Since, 55km is driven in 1 day

Hence, 990km = 990/55 = 18 days

Therefore, Mr. White travelled to work = 18 days

4. Let no. of days to travel 990km be x.

An equation: 990/55 = x

x = 18 days
