Question

a bridge currenly has 975 vehicles traveling on it per hour during peak time. a traffic engineer estimates that there will be 3.4%more vehicles traveling on the bridge for two years. How many more cars will travel on the bridge per hours during peak time in 2 years than are traveling now? Round your final answer to the nearest whole vehicle.

Answer 1

To determine how many more cars will travel on the bridge during peak time in two years, you will find what 3.4% of 975 vehicles is for the first year.

Add this number to the 975, and then multiply 0.034 times the new number of vehicles.

Here is the math:

0.034 x 975 = 33.15

This round to 33 more vehicles.
975 + 33 = 1008

0.034 x 1008 = 34.272

There will be about 33 + 34 (67) more vehicles on the bridge in two years.

Answer 2

Answer: In 2 years, 33 more cars will travel on the bridge per hours during peak time .

Explanation:

Hi, to answer this question we have to analyze the information given:

• Current vehicles: 975
• Percentage of increase: 3.4% = 0.034 (decimal form, 3.4/100=0.034)

So, first we have to multiply the number of current vehicles by the percentage in decimal form:

Mathematically speaking:

975 x 0.034 =33.15 ≅33 more cars (rounded)

If we want to know the total number, we simply add them to the current number of vehicles.

975 + 33.15 =1008.15≅1008 cars.
