Question

a. What is measured on the horizontal axis?

b. What is the range of value on the horizontal axis?

c. What is the temperature of the tea after $20$min?

d. How many minutes were needed to reach a temperature of $45°C$?

Short answer

a. The time is measured in min, on the horizontal axis.

b. The range of value on the horizontal axis is $0‐98$min.

c. The temperature of the tea after $20$min is $56C$.

d. $40$minutes were needed to reach a temperature of $45°C$.

Step-by-step solution

Part (a) step 1: Given Information

We need to find measured on the horizontal axis.

Part (a) step 2: Explanation

On the horizontal axis, the time is measured in min.

Part (b) step 1: Given Information

We need to find the range of value on the horizontal axis.

Part (b) step 2: Explanation

From the graph is understand the range of time is $0‐98$min.

Part (c) step 1: Given Information

We need to find the temperature of the tea after$20$min.

Part (c) step 2: Explanation

From the graph is understand the temperature after$20$min is$56C$.

Part (d) step 1: Given Information 

We need to find how many minutes were needed to reach a temperature of $45°C$.

Part (d) step 2: Explanation

We need $40$min to reach $45°C$, from the graph.
