Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 =
; y = 20 sin 45 ; y= 14.14 miles
cos 45 =
; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
=
+ 
=
+ 
= 3131.08
= 
z = 55.96 miles

The probability the next customer pays using a debit card based on the last three weeks is 30% or 0.3.
<h3>What is a probability?</h3>
This is the chance or likelood for an event to occur. For example, if in a city it has snowed every year on December 25th, there is a high probability it will snow this year and in the next years.
<h3>How to calcuate the probability?</h3>
Total of a specific outcome/ total of outcomes
Based on this, let's calculate the probability the next customer pays using the debit card:
- Total that pay with debit card: 21 customers
- Total of customers: 70 customers
- 21/ 70 =0.3 or 30%
