The respiration rate of mangoes, R (mg CO₂ kg⁻¹ h⁻¹), follows a Q₁₀ relationship. Between 5 °C and 15 °C the Q₁₀ value is 2.5, and between 15 °C and 25 °C the Q₁₀ value is 1.8. At 5 °C the respiration rate is 10 mg CO₂ kg⁻¹ h⁻¹. The maximum acceptable respiration rate for safe storage is 30 mg CO₂ kg⁻¹ h⁻¹. Determine the highest temperature (in °C, to one decimal place) at which the respiration rate does not exceed the limit.
