Cars A B C D
Speed (in km/h) 60.34 60.32 60.33 60.35


If the speedometer can only measure to the nearest tenth of a second, which car will have a different measurement?

D, If you round the numbers, they all round to 60, except for the last one, which rounds up to 61.

Answer:

Step-by-step explanation:

Given that Charles wants to determine which car is the fastest. The actual speed of four cars is shown below:

Cars                           A                 B          C         D

Speed (in km/h) 60.34 60.32 60.33      60.35

Speed (in m/s)         16.761      16.755    16.758     16.763

Rounded off            16.76        16.76      16.76        16.76

When measured in km/hour, the order from least to greatest is

B, C, A and D

When measured in m/sec, when rounded off to nearest 10th we get

all are having equal speeds.
